Remarks

For elements rendered as a single box, the IHTMLCSSStyleDeclaration::backgroundOrigin property specifies the background positioning area. For elements rendered as multiple boxes (for instance, inline boxes on several lines or boxes on several pages), this property specifies which boxes determine the background positioning areas.

If the IHTMLCSSStyleDeclaration::backgroundAttachment value for an image element is "fixed", then the IHTMLCSSStyleDeclaration::backgroundOrigin property has no effect. In this case, the background positioning area is the initial containing block.
